Objectives:
Students will identify various
shells.
Students will complete a K-W-L
chart.
Vocabulary:
mollusk- the soft bodied water animal that grows
a seashell
Conchology- the scientific study of shells
Materials:
K-W-L chart
Computer with Internet access
Paper and pencil
Seashells or pictures of shells
Literature Book- Ocean Day
by Shelley Rotner and Ken Kreisler
Procedure:
| 1. Begin a K-W-L (What I know about Shells..., What I Want to Know About Shells..., What I Have Learned About Shells...,). |
| 2. Provide students with a K-W-L handout. |
| 3. Teacher will hold up a seashell to
introduce the unit. Ask the students to write down all that they know about the shell that is being held up and what they wish to know about the shell. |
| 4. Teacher then reads the Ocean
Day book aloud to the class as an introduction. This book
will transport the students to the ocean through the photos. They will learn about waves and tides, grasses and sand dunes, tide pools and the creatures that live there, and seashells that can be found on the shore. |
| 5. Students can learn more about tidal pools by visiting the Enchanted Learning Intertidal Zone web site. |
Evaluation:
Teachers will evaluate students'
answers to questions on the K-W-L chart.
Extension:
Students can begin a shell card file on each shell that they learn about on
index cards. They can draw, color and record interesting facts about their
shell. These 3/5 cards are then assembled into a class file to be used in future
research. Students can also create a simple database to record and share their
shell information. Teachers can set up a database template for students to use
or data can be recorded and organized in tables created in word processing.
Home Learning:
Students may bring in shells
from home. Give students shell classification charts or have them log onto ArcherdShellCollection
and ArcherdShellCollection/ShellClass
to classify their shells in class. If students do not have shells to bring in,
have a class collection available to them. Try to have examples of bivalves,
chitons, tusk shells, snails, and cephalopods.
